Existence and uniqueness of periodic orbits in a discrete model on Wolbachia infection frequency

open access: yesAdvances in Nonlinear Analysis, 2021
In this paper, we study a discrete model on Wolbachia infection frequency. Assume that a periodic and impulsive release strategy is implemented, where infected males are released during the first N generations with the release ratio α, and the release is

On the Dynamics of Sexually Transmitted Diseases Under Awareness and Treatment

open access: yesFrontiers in Applied Mathematics and Statistics, 2022
In this paper, we develop and extend the work of Jia and Qin on sexually transmitted disease models with a novel class of non-linear incidence. Awareness plays a central role both in the susceptible and the infectious classes.

Dynamical, Stability, and Bifurcation of a Viral Model With General Cell‐to‐Cell Incidence Rate and Delayed Saturated CTL Immunity

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2025, Issue 1, 2025.
In this paper, we propose a viral model with cell‐to‐cell propagation, delayed saturated CTL immunity, and general incidence rate. Two biological threshold parameters, namely, the basic reproductive number R0 and the CTL immune reproductive number R1, are derived.

Bayesian Inference for SIR Epidemic Model with dependent parameters

open access: yesMoroccan Journal of Pure and Applied Analysis, 2022
This paper is concerned with the Bayesian inference for the dependent parameters of stochastic SIR epidemic model in a closed population. The estimation framework involves the introduction of m − 1 latent data between every pair of observations. Kibble’s

Determination in Galicia of the required beds at Intensive Care Units

open access: yesAlexandria Engineering Journal, 2021
By using a recent mathematical compartmental model that includes the super-spreader class and developed by Ndaïrou, Area, Nieto, and Torres, a procedure to estimate in advance the number of required beds at intensive care units is presented.

Coastal fisheries adaptations to increasing climate change exposure in Japan

open access: yesPeople and Nature, Volume 6, Issue 6, Page 2339-2356, December 2024.
Abstract Climate change‐driven ocean warming is altering the geographic ranges of species, leading to a poleward shift of tropical species into temperate regions (tropicalisation). This threatens the native marine community assemblages by changing the availability of traditional marine resources, thus impacting the livelihood and well‐being of coastal ...

A food chain ecoepidemic model: infection at the bottom trophic level [PDF]

open access: yes, 2014
In this paper we consider a three level food web subject to a disease affecting the bottom prey. The resulting dynamics is much richer with respect to the purely demographic model, in that it contains more transcritical bifurcations, gluing together the ...

Are the upper bounds for new SARS-CoV-2 infections in Germany useful?

open access: yesComputational and Mathematical Biophysics, 2021
At the end of 2019, an outbreak of a new coronavirus, called SARS–CoV–2, was reported in China and later in other parts of the world. First infection reported in Germany by the end of January 2020 and on March 16th, 2020 the federal government announced ...

From pandemic to a new normal: Strategies to optimise governmental interventions in Indonesia based on an SVEIQHR-type mathematical model

open access: yesInfectious Disease Modelling, 2022
There are five different forms of intervention presently realised by the Indonesian government in an effort to end the COVID-19 pandemic: vaccinations, social restrictions, tracings, testings, and treatments.
